Web server and Exchange behind an ADSL router

Hi all:

 

I finally was able to go through the basic configuration of my new cisco ASA 5515 X (i'm completely new to cisco devices). 

 

I also managed to create VPN's to my two Amazon VPC sites. This was particularly hard because my ADSL Router which this Cisco firewall is behind was making trouble.

 

Finally, all I had to do is reboot the ADSL Router and it all started working, but I had a hard time to find out the source of the problem (the guys at Amazon did the job, to be honest)

 

Now I face the next step, opening my web server and exchange server to the world. How is this done? Do I need to do something special because of the ADSL router?

 

Thank you.

On the ASA you'd do this with an ACL

object-group service EXCHANGE_SERVICES tcp

 port-object ew www
 port-object eq imap

...etc etc
 

access-list outside_in extended permit tcp any host 192.168.203.24 eq www

access-list outside_in extended permit tcp and host 192.168.203.11 object-group EXCHANGE_SERVICES

access-group outside_in in interface outside

 

You'd also have to allow access in from your ADSL router.
